Designed for legacy desktop and laptop upgrades

The YINGHUA AR9223 is a half Mini PCI-E wireless adapter that delivers 300Mbps theoretical throughput on the 2.4GHz band using 802.11a/b/g/n standards. It targets owners of older systems needing a basic wireless refresh without modern bandwidth demands.

Sustained throughput with 2x2 MIMO stability

Under continuous load the card maintains a bidirectional link up to 180M measured in point-to-point tests, with single-direction flows exceeding 90M. The AR9223 chip manages dynamic frequency selection and transmit power adjustment to keep the connection stable during long transfers.

Dual U.FL ports and ROS 4.0X compatibility

Two U.FL antenna connectors support the included 6dB antennas for a total MIMO output of 200mW. The PCI interface identifier 70 ensures mechanical fit in compatible slots, while driver support spans Windows XP through Windows 10 in both 32-bit and 64-bit editions.
